Explanation:
Tech Social Media giant FB is one of those companies. Not long ago the ceo was brought to court to accusations that his company was selling user data. Turns out this is true and they are selling their users private data to companies all over the word. Once the news turned to something else, people focused on something new but the company still continues to sell it's users data the same as before. This is completely unethical as the information belongs to the user and they are not getting anything while the corporation is profiting.
Answer:
a
Hardness Test
b
The available hardness test are
- Rockwell hardness test
- Vicker's hardness test
- knoop test
- scratch test
- Brinell hardness test e.t.c
I would suggest Rockwell test because
- It has good accuracy
- In this test loads can be applied in 2 stages hence better results are obtained
- it saves time because it testing are faster
c
Well the following would be the reasons for low hardness value
- It could be because the steel used has a low percentage of carbon
- it could also result from the quenching medium used (e.g water , brine solution e.t.c)
d
In order to solve this problem here are the following ways
- When selecting steel the ones with a carbon percentage 0.3% to 0.8% should be selected
- When quenching the quenching medium should be brine solution
Explanation:
The reason why the answer to question is hardness test is because the heat treatment was carried out to obtain hardness so if it is great then the heat treatment is good
